DALLAS — The world's largest wind farm officially got up and running Thursday, with all 627 towering wind turbines churning out electricity across 100,000 acres of West Texas farmland.

The Roscoe Wind Complex, which began construction in 2007 and sprawls across four counties near Roscoe, is generating its full capacity of 781.5 megawatts, enough to power 230,000 homes, the German company E.ON Climate and Renewables North America said.

The complex is about 220 miles west of Dallas and 300 miles south of the land where billionaire oilman T. Boone Pickens had planned an even larger wind farm before he scrapped the idea in July.

Texas leads the nation in wind power production, and this wind farm tops the capacity record of 735.5 megawatts set by another West Texas farm southwest of Abilene.
